Abstract

L'invention concerne des dispositifs à ultrasons présentant un ensemble transducteur comprenant un empilement d'électrodes alternées et d'éléments piézoélectriques. Un dispositif de montage présentant une première et une seconde extrémité est conçu pour recevoir une vibration ultrasonore en provenance de l'empilement et pour la transmettre de la première à la seconde extrémité. Un boulon (106) comprenant une tête et un axe est conçu pour venir en prise par filetage avec le dispositif de montage. L'ensemble transducteur (182) comprend un élément de pression déformable (100) présentant un orifice central qui permet l'insertion de l'axe et présente un côté convexe faisant face à la tête de boulon et un côté concave faisant face à l'empilement dans un état non déformé, mais, dans un état déformé, applique des forces de compression sur l'empilement en fonction de la déformation. L'élément de pression déformable (100) peut dans une variante comprendre une surface, dans son état déformé, sensiblement équivalente à la surface d'un élément piézoélectrique et/ou une première et une seconde surface biseautée définissant le côté concave.
